COIL AND COIL SHAPING METHOD

摘要

[PROBLEMS] To simplify the production work of a coil and to miniaturize a reactor, or the like, by reducing the occupation space as much as possible. [MEANS FOR SOLVING PROBLEMS] A reactor coil (12) consists of a first coil element (121) and a second coil element (122) formed by winding one flat type wire (17) rectangularly edgewise thereby stacking it in rectangular tube shape. At the end-of-winding of the first coil element (121), the flat type wire (17) is bent by about 90° in the direction reverse to the winding direction of the first coil element (121), and wound rectangularly edgewise in the direction reverse to the winding direction of the first coil element (121) so that it is stacked in the direction reverse to the stacking direction of the first coil element (121) thus shaping the coil in such a state as the first coil element (121) and the second coil element (122) are arranged continuously in parallel at the moment in time when winding of the second coil element (122) is ended.
